CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 301,737, dated July 8, 188%.

Application filed April '28, 1 884. (No model.)

To aZZ whom it may concern:

Be it known that I, Tnornis L. MoKnEu, a citizen of the United States, and a resident of Eastomin the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Gar-Couplings;

and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of the front part of a railway-car fitted with my improved automatic car-coupling, the car-platform being partly broken away to show the coupling. Fig. 2 is a perspective view of the coupling removed from the car. Fig. 3 is a similar view of the under side of the same, and Fig. 4 is a longitudinal sectional view showing two of the couplings in their coupled position.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation-to so-called automatic car-couplings, or self-couplers, of that class which are adapted more especially for use upon passenger-cars and coal-cars; and it consistsin the improved construction and combination of parts of a coupler of that class, as will he hereinafter more fully described and claimed.

In. the accompanying drawings, A denotes the front part of a car, (which, in the present instance, is a passenger'can) and B a portion of the platform of the some.

C denotes one of the buffers or bumpers,

.which may be of any desired construction;

but I prefer to use the improved buffer which forms the subject of another application for the sides of the link are two arms, I and-J,

, fingers L, which grasp and hold the'link so as to form a guide and keeper for the same, the lower part of the link resting upon the crossbar K between the arms I and J. The bolt G, upon which arms I and J are fastened, has a projection, M, which is bent at right angles to form the forwardly-projecting arm, N, which is parallel to the arm J and to the link. Arm N has at its outer end a pin or projection, 0, adapted to be hinged to the lower end of the chain or rod P, by means of which the coupling is operated from the platform of the car by means of the lever Q.

From the foregoing description, taken in connection with the drawings, the manner of operating, my improved automatic coupling will be readily understood. It will be seen that the arms I and .I, with their connecting cross-bar K, and bent lips or fingers L L, serve the twofold purpose oi uncoupling the link by elevating its free end sufficiently to throw it out of engagement with the hook opposite, and of so adjusting the elevation of the free end of the link as to cause it to properly engage the coupling opposite when the cars come together for the purpose of coupling them in making up a train. The bent fingers L L, by grasping the link on opposite sides,'0perate as a combined guide and keeper for the same, limiting its upward play relative to the arms I and J 5 and it will be seen that said arms, with their connecting cross-bar K, are actuated by operating arm N by means of its lever or operating mechanism 1 and Q.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States:

1. The combination, in an automatic car coupling, of the coupling-hook F, bolt G, inserted transversely through the same, link or bail H, hinged with the inner ends of its arms upon bolt G, and parallel arms I and J, connected at their outer ends on opposite sides of the link by cross-bar K, adapted to support the free end of the link, and fastened with their inner ends upon the bolt or opposite link, and the mechanism for operating boltG IO sides of the hook, substantially as set forth. and its attachments, substantially as set forth.

2. The combination, in an automatic ear- In testimony that I claim the foregoing as coupling, of the coupling-hook F, bolt G, my own I have hereunto affixed my signature having projection M and arm N, link .or bail in presence of two Witnesses.
